Porto has turned blue on more than one occasion this year, after a series of dramatic trophy wins by FC Porto during the 2010-2011 season. Managed by 33-year-old Andre Villas-Boas in his first ever season as a manager, FC Porto has achieved a trophy treble (their second ever), including the league championship, Europa League cup and the Portugal Cup. They also won the league opener – the Super Cup – at the beginning of the season. They are also the first team to complete a Portuguese league season undefeated since Benfica in 1973.

Thousands of “Portistas” descended on Aliados square in the centre of Porto for a celebration of flag waving, horn beeping and all-round fun in early April after FC Porto secured the Liga Zon Sagres championship, with five games still to play.

The celebration was captured in a photo featured on the Blog dos Campeões, and many fans turned to Facebook to share their appreciation of the team’s success.

The day after FC Porto won the championship (at the home of fierce rivals Benfica, of all places) Porto saw many people going to school and work wearing their FC Porto blue scarves.

Fans had two further occasions to turn out at Aliados this week when Porto beat neighbours Braga in Dublin to secure the Europa League trophy, and then following Sunday’s 6-2 demolition of Vitória Guimarães in the Portugal Cup final on Sunday at the National Stadium.

Next year should mean another big year for Porto, but doubts remain over the future of manager André Villas-Boas, because many expect a larger European team to try to poach him. Star midfielder Hulk has recently signed a new five year contract.
